Description

Up for sale is a Sequential Circuits Prophet‑600 Analog Poly Synthesizer, sold AS‑IS for Parts or Not Working. The unit does NOT currently power on. It was recently inspected by a local technician, who identified several issues that will need to be addressed for restoration.

Below is the full list of findings from the technician:

• Power supply needs repair after the rectifier; power rail voltages are out of spec

• Internal battery needs replacement

• Previous repairs to the output jack and internal battery area require attention

• Corrosion present on multiple circuit boards

• Broken pot shaft for the frequency control

• Positive notes: all chips are present, most knobs are intact, no broken keys, and many usable parts remain

Cosmetically, the synth is in Good vintage condition, showing typical wear for its age. The panel, keys, and chassis look solid overall. Please review all photos for the most accurate representation of its condition.

This is an excellent candidate for restoration, parts harvesting, or a project for someone experienced with vintage analog synthesizer repair.
